asked the Secretary of State for the Environment if he will make a statement on the details supplied to date by his Department, concerning estimates of future energy demand and fuel mix required, as input to the individual studies comprising the Fellowship of Engineering's project entitled, "Acidic Emissions: Study of Combustion Processes and Abatement Technologies"; and if he will outline progress with the project and the results which have so far been produced.

Estimates of future energy demand and fuel mix have not been required for any of the individual studies within the fellowship's project and none have been suplied by the Department. The final report is due to be submitted by 31 March 1988, but good progress by the fellowship means that the detailed technical and economic assessment of abatement technologies will probably be available earlier.
